Language:

Description:
The aim of this study was to compare the central and peripheral components of cardiorespiratory fitness during incremental to maximal exercise between older men who were either recreational athletes (RA) or leisurely active (LA) men, i.e., those who fall between trained and untrained. This was a crosssectional study in which all subjects completed an exercise test on a cycle ergometer. Maximal oxygen consumption (VO2max) and ventilatory threshold (VT) were assessed using gas analysis, and central components of VO2max were assessed using a non-invasive thoracic bio-impedance device. VO2max (RA: 45.1±4.8 ml/kg/min; LA: 32.2±4.6 ml/kg/min, p≤0.001) and SV at maximal exercise (RA: 133.5±24.96 ml/beat; LA: 107.9±17.6 ml/beat, p=0.005) were higher in the RA group compared to the LA group. A plateau in SV occurred between 30-45 % of maximal exercise capacity in the RA group. No differences in SV were observed across workloads in the LA group. No differences in the calculated arterio-venous oxygen difference ((a-v)O2diff) were observed between groups. In conclusions, training volume appears to influence central components of cardiorespiratory fitness among a matched sample of older men who are neither trained nor untrained. This builds a case for increasing the volume of training to preserve cardiorespiratory fitness among older men., C. D. O'neill, D. S. Kimmerly, S. Dogra., and Obsahuje bibliografii

3575. Central European historian Bedřich Loewenstein (1929-2017)

Description:
The author summarizes the life and in particular scientifi c career of historian Bedřich Loewenstein, describes areas of his professional interest and his intellectual orientation, reminds of his most important works published in Czech and German, and assesses his contribution. Loewenstein was born in 1929 in Prague, in a Czech- -German-Jewish family, lived through the German occupation in diffi cult conditions, and started studying history and philosophy at what was then the Faculty of Arts and History of the Charles University, but was expelled two years later for political reasons. He was allowed to complete his studies later, and in 1957 started working at the Institute of History of the Czechoslovak Academy of Sciences, where he remained until his dismissal in 1970. He started intensive contacts with West German historians and other intellectuals during the 1960s, and organized an important international symposium, ''Europe and Fascism'', in Prague in 1969. Since the early 1970s, he was not allowed to publish and was employed as an interpreter/translator of the trade mission (since 1973 embassy) of the Federal Republic of Germany. Although watched by the State Security, he managed to make use of his position to establish an important connection between domestic dissenters and their supporters abroad, which was used to exchange publications and other documents. In 1979, he accepted an offer of professorship of recent history at the Free University in West Berlin, where he remained until 1994 and where he could develop and expand his research interests and devote himself to intensive publication activities. For a long time, Bedřich Loewenstein was focusing on the German history of the 19th and 20th centuries; since the 1960s, he was also studying ideological, psychological, and social prerequisites of Nazism and later also more general issues of crises of the 20th century, modernism and modernity, civic society, European nationalism, and civilization. In this respect, he was able to integrate approaches and knowledge of other social sciences - sociology, social psychology, anthropology, philosophy, political science, and economy - in a prolifi c manner. He was a long-time and intensive intermediary of views and ideas between the Czech (or Czechoslovak) and German historiographies. His works, written in a concise, scientifi c-essayist style, earned him respect among colleagues both at home and abroad. His principal works include Plädoyer für die Zivilisation (Hamburg, Hoffmann und Campe 1973), Entwurf der Moderne: Vom Geist der bürgerlichen Gesellschaft und Zivilisation (Essen, Reimar Hobbing 1987; in Czech in 1995), Problemfelder der Moderne: Elemente der politischen Kultur (Darmstadt, Wissenschaftliche Buchgesellschaft 1990), My a ti druzí: Dějiny, psychologie, antropologie [We and the others: History, psychology, anthropology] (Brno, Doplněk 1997; in German in 2003). A synthesis of Loewensteinʼs thinking about a broad spectrum of issues is presented in his book Der Fortschrittsglaube: Geschichte einer europäischen Idee (Göttingen,Vandenhoeck & Ruprecht 2008; in Czech: Víra v pokrok: Dějiny jedné evropské ideje [Faith in progress: The history of a European idea]. Praha, OIKOYMENH 2009). and Překlad: Jiří Mareš

Subject:
central fatigue, fatigue indicators, drowsy driving, and signal analysis
Language:
English
Description:
The airn of the research described in this work is to find the estimator of the fatigue level of a huiiian operátor driver. The deniand of nonintrusive approach constraiiits the existing possibilities. It is demonstrated that a small steering wheel movement compeiisating heading error carry Information on driver fatigue. The biological origin of fatigue is described and a simple method for calibration of fatigue based on the fuzzy approach is submitted. With the help of one type of fatigue indicators a possibility to identify the fatigue caused by sleep deprivacy is demonstrated.

3578. Centralizace vědy - státní společenskovědní ústavy a vznik ČSAV: osudy Slovanského a Orientálního ústavu v letech 1945-1953

Subject:
Oriental Institute, Slavonic Institute, Czechoslovak Academy of Sciences, and centralization of science
Language:
Czech
Description:
Slovanský a Orientální ústav prošly od svého vzniku do roku 1953 mnohými obměnami a to jak ve smyslu organizačním, tak změnami hlavního směřování badatelských záměrů, násilnou obměnou členské základny i změnami ve financování. Studie se zabývá otázkou příčin a důsledků organizačních změn vedení obou ústavů v průběhu jejich vývoje od skončení druhé světové války po začlenění do Československé akademie věd. Studie se zabývá problematikou vybraných jevů - jak se tyto změny promítly například v nahlížení na samotné začlenění obou ústavů do Akademie věd, jak a kdy probíhala změna těchto zpočátku spíše ''prestižních'' ústavů v ústavy vědecké a co ústavům toto začlenění v širší vědecké organizaci dalo či naopak vzalo. and From their establishment until 1953 the Slavonic and Oriental Institutes underwent numerous changes in the organizational sense, as well as involving the primary direction of research objectives, the compulsory replacement of the membership base and funding. This study deals with the issues surrounding selected phenomena - how these changes were reflected e.g. taking into account the actual incorporation of both institutes in the Academy of Sciences, how and when these initially rather ''prestigious'' institutes turned into ''scientific institutes'' and what they won and lost from this incorporation within larger scientific organizations

Description:
CORDIS, a new service Unique Registration Facility (URF), was launched on April 27. It will facilitate the preparation of grant agreements between participants and the European Commission. Thanks to the new service, participants in the Seventh Framework Programme (FP7) and other programmes managed by the Research Directorate General will no longer have to submit their legal and financial information each time a new grant agreement is in the pipeline. Once participants have been validated by the European Commission´s central validation team for their existence as legal entities and their legal status they will only have to submit their Participant Identification Code (PIC). and Lenka Lepičová.
